摘要
套管损坏的主要类型可归纳为变形、破裂和密封性破坏3类。分析了射孔对套管损坏的影响,提出了合理选择射孔弹及射孔枪、改进套管柱设计方法、对下井套管要进行严格质量检验、提高套管抗挤强度等具体措施来减少套管的损坏。
Configuration of casing damage can be in three categories： deformation,break and seal damage. This paper analyzed the effect of perforation on easing,proposed several measures which can be used to decrease easing damage, such as selecting reasonably perforation gun and bullets, improving easing program, inspecting rigorously easing quality, raising easing strength, and so on.
